Abstract
A new lighting system is provided that is particularly useful in projecting light to a deck where pilots use night vision goggles (NVGs). The system comprises a pair of subsystems that project light with different, complementary spatial distributions. One subsystem projects light with one spatial distribution, and the other lighting subsystem projects light with another spatial distribution that supplements the light from the first subsystem, so as to provide a system that effectively illuminates an entire target. The system is designed to substantially filter light so that the light does not interfere with NVGs. The system includes new optical projection structure that minimizes the overall size of the projection structure, and maintains good efficiency.
